my kingdom for an xr2 engine (though a friend has just written off his rs turbo.. watch this space) ... My Q is fitted with the standard 1.4 cvh!
Have checked all the connections and liberally dosed them with wd40. Still no fix so I suspect I may be stripping the carb. I think for the future I will lure the good lady out with coffee and biscuits to work the pedal to bleed the brakes. She had her first ride in the Q yesterday and after discovering that she needs to put her hair up in a soft top she quite enjoyed the attention we were getting. Just waiting for the piece of paper from FJ then I can get some Tax and I think the seaside beckons.
